For anyone else wondering the same thing I was (when?) - I believe I found the answer on IGN:

9 am Eastern / 6 am Western (and 2 PM GMT if anyone on these forums is from that area... Is anyone here not in the Western Hemisphere? It just occurred to me I've been assuming the whole time.... Not that it matters in the slightest.)

I wouldn't go in expecting any news on Pikmin 3. This is primarily a 3DS Nintendo Direct. From what I've heard, Japan and Europe's Directs won't talk about the Wii U at all, only NA. It would be weird and unlikely for NA to get any exclusive info for Pikmin 3 that Japan and Europe don't get.

That's a fair point, but considering that the NA show is going to have some Wii U info, I wouldn't be surprised if it were info on games that we already know about. With Pikmin 3 expected to drop sometime during the Spring (at least in Japan), it would make sense to start rolling out some info about the North American release soon.
